IMPROVED 'GAS-MACHINE.

The Schedule referred to :in these Letters Patent and making part of the same.

4to the accompanying drawings, and to the letters of reference marked thereon, and being a part of this specification, -in which- Figure 1 is a vertical section, taken on the line :v x in tig. 2,*of the tank, with the gasometer and carburetting-chamber partially broken away, toshow their internal arrangement.

Figure 2 is a planof the apparatus.

Like letters indicate like parts in `each figure.

lhe nature of this invention relates to an improvement in the construction. of machines for carburett-ing atmospheric with the vapor of gasoline or other liquid hydrocarbons, and consists in the peculiar arrangement, within a proper tank and gasometer, of a carburett-ingchamber and a series of filling and pelforated distributing-pipes, one of the latter' delivering the air, forced through the same, in the form of jets, into the body of the liquid hydrocarbon contained in the carburetting-chamber, for the purpose of intimately mixing the air with said liquid, and in its passage through the same it becomes charged wit-h its vapor. rlhe mixture, being iuannnable, is used for illuminating-purposes, after being rid of its impurities, which is ciiected by passing it'tln'ough water into the gasorneter, in the form of jets, through and by means of'ia perforated pipe provided for that purpose.

A represents a suitable water-tank, within and op' the bottom of vwhich is placed a tight carburettingchamber, B, divided into an "upper and lower chamber `by a perforated diaphragm, a, the latter of which is partially iilled with gasoline or other volatile liquid hydrocarbon, through the tilling-pipe b.

c isa pipe through which air is forced into the carhuretting-chamber, by any suitable air-pump, and enters said chamber at the bottom, where it branches'oii` into a pair of perforated pipes, c', so that the air, in rising through the gasoline in numerous jets, becomes thoroughly charged with its volatile and intlammable va or.

l']).he mixture then passes into theupperchamber, or reservoir, whence it is taken, vby tl1c"siphonpipe d, to the bottom of the tank, and is discharged through the perforated pipe d', which surrounds the carburett-ing-chamber, into the water with which the tank is pm-tiailyued.

Into this water the impurities are precipitatedas the gas or inflammable mixture rises into the gasometer C, whence it is distributed, by the supply-pipe e, 'to the several burners. l

Should it become necessary to empty the carburet-l ting-chamber of its contents, they may be pumped out through the pipe b, or a pipe and stop may be connected with theI chamber for that purpose.

The various pipes are provided with the necessary stop-cocks, as shown, which are preferably placed in them, above the top of the tank, for convenience of manipulation. t

What I claim as my invention, and desire to secure by Letters Patent, is-

The construction of XVitnesses:
